You know the feeling: you finish a hard workout, or you've been fasting past noon, and your head goes fuzzy and your legs feel like they belong to someone else. You drink water and it doesn't help, it almost makes it worse. That's usually the moment people start hunting for an LMNT electrolytes review, hoping there's something better than plain water for this specific kind of tired.
Here's the bit the listing buries under all the energy talk: this isn't really a hydration product, it's a sodium product. Each stick pack has 1000mg of sodium, 200mg potassium and 60mg magnesium, which is a lot more salt than a typical sports drink. That's deliberate. When you sweat, you lose sodium faster than you lose water, so drinking plain water just dilutes what's left, which is exactly what causes that foggy, crampy, dizzy feeling. LMNT's ratio is built to replace what actually left your body, not just top up volume. That's why it matters most for people on low-carb or keto diets (who flush sodium faster once carbs and the water they hold are gone), people fasting, and anyone sweating heavily in training or heat. You mix one packet into 16 to 32 ounces of water, sparkling water or tea, and because there's zero sugar, it doesn't undo a fast or a carb-restricted day the way a regular sports drink would. The watermelon salt flavor is just the vehicle, the sodium dose is the actual product.
So you're not buying a flavored electrolyte drink, you're buying a calibrated dose of salt for a body that's losing more of it than average. If your day doesn't involve heavy sweat, fasting or carb restriction, you're probably not running that deficit, and the extra sodium is just extra sodium. The whole question is whether your daily sodium losses actually match what's in the packet.
Worth it if
- You train hard or sweat heavily and regular water leaves you flat
- You're on a keto or low-carb diet and losing sodium faster than usual
- You fast regularly and want electrolytes without breaking a fast on sugar
Skip it if
- You're sedentary and already get plenty of salt from food
- You're managing blood pressure or sodium intake under medical advice
- You just want a lightly flavored drink, not a sodium dose
Not for people managing sodium intake for medical reasons, or anyone who just wants a light-tasting hydration drink
If you train hard, fast regularly, or eat low-carb and recognize that foggy, cramped feeling, this is a quiet yes and it'll earn a permanent spot in your gym bag. If you're generally sedentary, already salt your food freely, or you're watching sodium for a health reason, save your money and stick with water. Either way, you now know what that big sodium number is actually for.

Before you go
Can you drink LMNT every day?
Most people who sweat regularly or eat low-carb can, since the sodium is designed to replace what's actually lost, but if you're not sweating much or you're watching sodium intake, daily use adds more salt than you likely need.
Is LMNT better than Gatorade Zero?
They're built for different things: LMNT carries far more sodium and no sugar, aimed at heavy sweat loss or keto and fasting, while Gatorade Zero is a lighter, more casual hydration drink, so 'better' depends on how much salt your day actually costs you.
